How come Mr. Squirrel watches porn sometimes?
Sometimes he feels like a nut, sometimes he don't.
Listen up, buttercup. This joke is all about a play on words. See, there's a double meaning going on with the phrase "feels like a nut". On the one hand, it's about a squirrel wanting to eat a nut. But on the other hand, it's a euphemism for feeling horny. I know you are slow, but try to keep up. And I know you love squirrels. You go out and put food for them every day. They probably hate you and think that you are really weird.
